Three Primary Materials for Solar Well Pump Bodies
Premium AISI304 Screw
- The screw pump body is made of stainless steel, which is highly corrosion-resistant and durable.
- It has strong adaptability to sand content and strong wear resistance.
- The structure is simple and easy to maintain.
- It is more suitable for conveying water containing sand and impurities
- It is suitable for working environments with small flow and high lift.
Premium AISI304 Impeller
- The pump body is made of all stainless steel.
- Excellent corrosion resistance.
- High strength and long service life
- Higher fluid dynamic performance and efficiency
- More suitable for drinking water applications than plastic impeller pump bodies when water quality and hygiene requirements are high
Premium Plastic Impeller
- Made of high-strength plastic
- Lightweight, easy to install and maintain
- Low cost, high cost performance
- Good corrosion resistance, suitable for a variety of water conditions
- Lower maintenance cost than stainless steel impeller
- Corrosion resistance to acidic and alkaline water is better than stainless steel pump body

How to Build a Solar Well Pumping System: 3 Key Steps for Off-Grid Water
1.How to Choose the Right Solar Well Pump Size
- Calculate your flow rate needs (gallons/liters per minute) based on specific application
- Measure required pressure to deliver water to desired locations (measured in PSI or bar)
- Identify usage patterns – irrigation systems require different specifications than household supply
- Consider seasonal variations in water demand for adequate year-round performance
2.How to Select the Right Solar Well Pump Extension Cord
- Match extension cord specifications to your pump and controller model
- Refer to our compatibility chart for proper wire gauge
- Choose outdoor-rated cords with waterproof connections for pool safety
3.How to Choose the Right Solar Panels for Your Pump
- Select solar array with at least 1.3x your pump’s wattage for optimal performance
- Ensure solar panel voltage matches pump and controller voltage requirements
- Position panels for maximum sun exposure to maintain consistent water flow
Example:
For a 72V, 1200W pump with 90-120V MPPT range and 160V max:
- Required solar array: minimum 1560W
- VMP voltage: above 72V (96-120V optimal)
- VOC voltage: below 160V safety threshold
